Preparation of Micron‐Sized Li4Ti5 O 12 and Its Electrochemistry in Polyacrylonitrile Electrolyte‐Based Lithium Cells

Publikováno v: Journal of The Electrochemical Society. 145:2609-2615

Micron-sized Li 4 Ti 5 O 12 was prepared in a single-step solid-state reaction involving TiO 2 and Li 2 CO 3 , and its electrochemical behavior was evaluated in Li and Li-ion cells containing a polyacrylonitrile (PAN)-based solid polymer electrolyte.

The Li4Ti5 O 12/PAN Electrolyte// LiMn2 O 4 Rechargeable Battery with Passivation‐Free Electrodes

Autor: K. M. Abraham, D. Peramunage

Publikováno v: Journal of The Electrochemical Society. 145:2615-2622

The Li-ion cell, Li 4 Ti 5 O 12 //PAN electrolyte//LiMn 2 O 4 , appears to be a classic example of a battery with passivation-free electrodes. Its gross impedance characteristics remain steady during long-term cycling at high charge/discharge rates.

Preparation and Electrochemical Characterization of Overlithiated Spinel LiMn2 O 4

Autor: D. Peramunage, K. M. Abraham

Publikováno v: Journal of The Electrochemical Society. 145:1131-1136

Parasitic reactions taking place at the carbon anode are primarily responsible for the capacity loss that occurs during the formation cycles of a carbon/LiMn 2 O 4 Li-ion battery. The additional amount of cathode material required to supplement this

Lithiated manganese oxide cathodes for rechargeable lithium batteries

Autor: K. M. Abraham, D. Peramunage, D. M. Pasquariello, Z. Jiang, T.H. Hguyen

Publikováno v: Proceedings of 11th Annual Battery Conference on Applications and Advances.

Lithiated manganese oxides Li/sub x/Mn/sub y/O/sub 2/ prepared at the low temperature of 400-450/spl deg/C exhibited significantly different electrochemical properties than the spinel phase, LiMn/sub 2/O/sub 4/, formed at 650-850/spl deg/C. The forme

Lithium-ion batteries based on overlithiated LiMn/sub 2/O/sub 4

Autor: E.B. Willstaedt, K.M. Abraham, D. Peramunage

Publikováno v: Thirteenth Annual Battery Conference on Applications and Advances. Proceedings of the Conference.

The irreversible capacity loss at the carbon anode in the C/LiMn/sub 2/O/sub 4/ cell can be compensated for with the use of the excess Li, x, in Li/sub 1+x/Mn/sub 2/O/sub 4/, where x is chosen to be equal to the irreversible capacity. The authors hav

Preparation and Battery Applications of Micron Sized Li4Ti5O2

Autor: D. Peramunage, K. M. Abraham

Publikováno v: MRS Proceedings. 496

The objective of this study was to highlight the usefulness of micron-sized Li4Ti5O12 in three distinctive areas: a) cathode of a low-voltage Li battery, b) insertion type auxiliary electrode to investigate the electrochemistry of oxide cathode mater
